Natalie Portman - Natalie Portman's Germ Fear

Natalie Portman's Germ Fear

Natalie Portman has become obsessed with germs.

The 'Black Swan' actress - who is expecting her first child with fiance Benjamin Millepied this summer - reportedly carries hand sanitizer everywhere she goes as a precautionary measure to prevent herself from catching any unwanted bugs in the lead-up to the birth of her baby.

An insider explained: "She's become a bit of a germaphobe. She carries hand sanitizer everywhere she goes and doesn't like to shake hands or stand to close to people."

However, the 29-year-old actress' fiance - who she met on the set of 'Black Swan', which he choreographed - is supporting Natalie's new found germ obsession and even rushed out to buy a humidifier for the couple's Los Angeles home.

The source added to National Enquirer magazine: "Ben's been great. He humours Natalie."

Natalie is not the only star to become a "germaphobe" after falling pregnant.

Shortly after Jennifer Lopez gave birth to twins Max and Emme in 2008, it was reported she had installed dispensers containing a special hand lotion for people to use before they entered the babies' nursery.

Jennifer and husband Marc Anthony are said to be so concerned about microscopic nasties they also request guests put on surgical masks before meeting the tots.

Gwyneth Paltrow - who is married to Coldplay star Chris Martin - wouldn't let anyone handle her children when they were babies unless they used a special soap beforehand to rid themselves of dirt.

She also insisted visitors remove their shoes before entering her London home.
